Helix
A self-hosted platform that runs a fleet of coding agents, each in its own GPU-accelerated sandbox desktop, coordinated through a spec-driven Kanban board so a team can review and merge their pull requests.
Helix runs coding agents on shared infrastructure instead of a developer's own laptop, giving each agent its own isolated sandbox with a full desktop: browser, terminal, filesystem and GUI applications. Work is organized in projects, each with a Kanban board where tasks move from backlog through planning, spec review, in-progress work and a pull request to merged.
A task starts as a short description of the desired outcome. A planning agent reads the connected repository and writes a specification to a branch for the team to review and revise; once approved, an implementation agent codes the change live in its sandbox, and a team member can watch, steer it, or switch to a different agent mid-session before a pull request is opened in the real repository.
It works with existing agent harnesses such as Claude Code, Codex, Gemini CLI, Qwen Code or other ACP-compatible agents, against self-hosted or hosted model providers, and can run fully self-hosted, including air-gapped.
